Zongshen RX3 : Unexpected Dead Engine in a deep forest tour

[vickytulla]

thanks man, yes I am on it.. spent a weekend trouble shooting, one of a car EFI technician helped out a lot, I also met a Honda/Yamaha Super bikes service center who do service for sports bikes they were least bothered to help out ..

any ways this car mechanic new and I gave suggestions which i read here by all you people.. and he totally agreed...

1 - [DONE] we replaced the relay any ways just to remove any doubts... (right now both relays do the "tick" "Click" on doing switch on/off ignition..

2 - then we dipped fuel pump into a bowl of petrol and wired it with battery it did not ran nor it made any BZZZ sound.. he shaked it blow air into its passages... then he said it seems like this thing is tucked.. I said how hw said it tries to move but then stop..

He had a carb cleaner he dissected the actuall motor out of the feul pump assemble and blew carb cleaner in it.. the again checked this time it produced "click" sound but did not moved or bzzzzzed...

then he again banged it against hand just like he was trying to get it moving some how.. this time when he dipped it in fuel and tested it spewed out fuel and started to rattle and bz..zzzzz....

on several further tests it was noticed that some times it will get stucked again and some times it will work.. when it gets stcuked if banged or shaked it will start working..

so final diagnoses is that feul pump has gone bad... any one nows if this pump is changeable/swap able from some other bike or car ? or do I have to get exactly the same ?

any guidance will be really really appreciated...
